VQ engine shouldn't be vibrate that much till you can felt it at the gear knob! He told you that it haven't been started for sometime, but after few minutes, it should stable down already. What you can do is, open up the engine oil cap and look at it and see is there any oil deposit around it. Next, pull the oil checking level stick out and see any oil deposit on it also, if either 1 you found some stuffs around it, then the engine is bad...or should I said it is time bomb!
Speaking of workshop, there are few HKS certified workshop over at HK and that's the best bet for you to get some modification done. Log on to HKS USA and search for International Dealers and all the address and company name will pop out there.
Good luck to you and have fun with the "lady"....
